Abstract

Des modes de réalisation de la présente demande concernent un procédé et un appareil de communication. Le procédé est appliqué à un système de communication comprenant au moins une chaîne de blocs. Le procédé comprend les étapes suivantes : un dispositif terminal génère une première demande, la première demande comprenant des informations d'une première chaîne de blocs, pour demander l'accès à la première chaîne de blocs ; le dispositif terminal envoie la première demande à un premier élément de réseau. Il est demandé que la première chaîne de blocs fasse l'objet d'un accès au moyen de la première demande, de telle sorte que le dispositif terminal accède à la chaîne de blocs dans une scène de fusion du système de communication, qui comprend le dispositif terminal et le premier élément de réseau, et la chaîne de blocs, de telle sorte qu'un opérateur crée une plateforme de partage de données sûre et inviolable pour le dispositif terminal au moyen d'une chaîne de blocs.
